The SK-400 Air-System Socket is the recommended socket for use with the 4-400A tetrode, and it may be used as well with 4-250A, 4-125A and other tubes having the same dimensions, like the 3-500zg, or 3cx1200A7. The SK-400 provides efficient connection between the tube and its external circuits, acts as a firm mechanical support for the tube, and controls the flow of cooling air around the tube envelope.
